Four 1 keyways of side core-pulling movable insert are slidably matched, and are moved with driving side core-pulling movable insert 1 to do interior receipts；The cone of four keyways
It is 7.5 ° to spend angle.
The mechanism is applied to be intervally distributed with back-off on product, especially truncated cone-shaped product core side full circle and need to demould
Application scenario.The length of bottom plate 16 is 50-120cm, width 50-120cm.
The driving of the mechanism needs the dynamic model side of mold to mold parting twice to realize central four sides tiltedly T-slot Loose core block
The inner core pulling demoulding functions of implementation mechanism are received in 3 four, four sides of driving side core-pulling movable inserts 1.
In actual work, the application method (course of work) of the mold is divided into following steps：
It is opened as shown in fig. 6, the mold that mechanism is applied has parting in five times altogether, is followed successively by PL1-PL2-PL3-PL4-
The removal of PL5, wherein PL1, PL2 for the runner waste material of mold, PL3, PL4, PL5 are the action drives parting of mechanism.
1) when mold molds, third time parting is opened to be opened at PL3 die joints, and when opening, the dynamic model of mold retreats,
The spring of dynamic model backing plate 12 struts down, and mold is opened at PL3 die joints, and dynamic model backing plate 12 is pulled through screw and is fastened on
Tiltedly T-slot Loose core block 3 retreats at center four sides thereon, and tiltedly T-slot Loose core block 3 is pulled from by dovetail groove K thereon at center four sides
Side core-pulling movable insert 1 acts, but its direction retreated is blocked by movable insert frame 2, therefore it can only be towards in movable insert frame 2
The heart in the horizontal plane to which four back-off grooves on four side core-pulling movable inserts 1 are detached from its molded part realize by mobile interior receipts
The demoulding of four recessed back-offs in side.
2) on product after tetra- back-off demouldings of A1-A4, mold is opened at PL4 die joints, realizes the de- of product cavity surface
Mould.
3) last mold is opened at PL5 die joints, the ejection upwards of core scraping wings 10, by product from movable insert frame 2
The complete demoulding of product is realized in upper release.
4) it resets, when reset, action process is opposite with the process of die sinking.
